T-Mobile is getting ready to launch a trackball replacement program that is sure to make a few BlackBerry users happy. The program will be valid for users of the BlackBerry Pearl 8100 and 8120 as well as the BlackBerry Curve 8320. Additionally, the user needs to have purchased the handset from T-Mobile.

In short, if you have one of those above listed models and have a janky trackball you can head on in to your nearest T-Mobile retail store and have it replaced for free. The replacement program will begin as of February 15, 2010.
